Description

本発明は、ブレードラバーに装着される板部材（バーティブラ）を備えたワイパーブレードに関する。 The present invention relates to a wiper blade including a plate member (vertebra) attached to a blade rubber.

ワイパー装置に備えられるワイパーブレードには、ブレードラバーに所定の適切な形状を付与するため、ブレードラバーに対して装着される板部材（バーティブラ）を備えたものがある。図９には、このようなワイパーブレードの全体構成を示す。図示されるように、ワイパーブレード１は、ブレードラバー２と、ブレードラバー２を支持する支持部材３と、ブレードラバー２の両側に取り付けられた一対のバーディブラ４とを備えている。 Some wiper blades provided in the wiper device include a plate member (vertebra) attached to the blade rubber in order to give the blade rubber a predetermined appropriate shape. FIG. 9 shows the overall configuration of such a wiper blade. As shown in the figure, the wiper blade 1 includes a blade rubber 2, a support member 3 that supports the blade rubber 2, and a pair of bar dibras 4 attached to both sides of the blade rubber 2.

ブレードラバー２は、ワイパーブレード１の使用時に、被払拭面（例えば自動車のガラス面）に沿って配置され、被払拭面の払拭を行うゴム製の長尺部材である。支持部材３は、複数のレバー（プライマリレバー３Ａ、セカンダリレバー３Ｂ、ヨークレバー３Ｃ）を積み重ねて構成されたもので、セカンダリレバー３Ｂ及びヨークレバー３Ｃの端部に設けられた爪状の係止部材３Ｄでブレードラバー２を支持している。また、プライマリレバー３Ａの長手方向中央部には、図示されないワイパーアームとの結合のための結合部材３Ｅが設けられている。バーティブラ４は、ブレードラバー２と略同じ長さの金属製板部材であり、ブレードラバー２の両側に長手方向に沿って形成された溝内に装着されている。 The blade rubber 2 is a long rubber member that is disposed along a surface to be wiped (for example, a glass surface of an automobile) and wipes the surface to be wiped when the wiper blade 1 is used. The support member 3 is configured by stacking a plurality of levers (a primary lever 3A, a secondary lever 3B, and a yoke lever 3C). The blade rubber 2 is supported in 3D. Further, a coupling member 3E for coupling with a wiper arm (not shown) is provided at the center in the longitudinal direction of the primary lever 3A. The vertebra 4 is a metal plate member having substantially the same length as the blade rubber 2, and is mounted in grooves formed along the longitudinal direction on both sides of the blade rubber 2.

図１０に示すように、バーティブラ４は、ブレードラバー２の両側に装着されたときに、ブレードラバー２に対して適切な形状を与えるように、湾曲した形状を有している。このようなバーティブラ４の湾曲形状は、単純なものではなく、バーティブラ４の長手方向の位置毎に、細かく曲率半径（Ｒ）が変えられた複雑なものとなっている。これにより、被払拭面との関係で適切な形状を付与されたブレードラバー２が、被払拭面に対して適切な押し付け力で当接して配置され得るようになっている。 As shown in FIG. 10, the vertebra 4 has a curved shape so as to give an appropriate shape to the blade rubber 2 when mounted on both sides of the blade rubber 2. Such a curved shape of the vertebra 4 is not simple, and is complicated with the curvature radius (R) being finely changed for each longitudinal position of the vertebra 4. Thereby, the blade rubber 2 provided with an appropriate shape in relation to the surface to be wiped can be disposed in contact with the surface to be wiped with an appropriate pressing force.

このように、従来のワイパーブレード１においては、バーティブラ４に対して複雑な形状の湾曲を付与する必要があったため、加工に手間がかかっていた。また、ワイパーブレードの種類が異なると、バーティブラの湾曲形状も異なってくるため、ワイパーブレードの種類毎にバーティブラを用意する必要があり、効率が悪かった。 As described above, in the conventional wiper blade 1, it is necessary to give a curved curve having a complicated shape to the vertebra 4. Further, since the curved shape of the vertebra is different depending on the type of wiper blade, it is necessary to prepare a vertebra for each type of wiper blade, which is inefficient.

本発明は、このような問題点に着目してなされたもので、ブレードラバーに装着される板部材（バーティブラ）を備えたワイパーブレードにおいて、複雑な湾曲形状の板部材を容易な加工で効率的に形成できるようにしたワイパーブレードを提供することを目的とする。 The present invention has been made paying attention to such problems, and in a wiper blade provided with a plate member (vertebra) attached to a blade rubber, it is efficient to easily process a complicated curved plate member. It is an object of the present invention to provide a wiper blade that can be formed into a thin film.

本発明は、ブレードラバーと、前記ブレードラバーを支持する支持部材と、前記ブレードラバーに湾曲形状を付与するために前記ブレードラバーに装着された板部材とを備えたワイパーブレードにおいて、前記板部材を、複数の板部材片と、前記複数の板部材片を連結する複数の連結部材とから構成した。 The present invention provides a wiper blade comprising a blade rubber, a support member that supports the blade rubber, and a plate member that is mounted on the blade rubber in order to impart a curved shape to the blade rubber. And a plurality of plate member pieces and a plurality of connecting members for connecting the plurality of plate member pieces.

前記連結部材は、前記板部材片の端部が嵌合する嵌合穴を備えてもよい。
前記連結部材と前記板部材片の端部のそれぞれに係止部を設け、これらの係止部の係合により、前記板部材片の前記連結部材からの脱落が防止されるようにしてもよい。 The connecting member may include a fitting hole into which an end portion of the plate member piece is fitted.
A locking portion may be provided at each of the connecting member and the end portion of the plate member piece, and the engagement of these locking portions may prevent the plate member piece from falling off the connecting member. .

前記ブレードラバーは、前記板部材が装着される溝部を備えるとともに、前記溝部上に連結部材装着部を設け、前記溝部に前記板部材が装着されたときに、前記板部材を構成する連結部材が、前記連結部材装着部内に配置されるようにしてもよい。 The blade rubber includes a groove portion on which the plate member is mounted, and a connecting member mounting portion is provided on the groove portion, and when the plate member is mounted on the groove portion, the connecting member constituting the plate member is Further, it may be arranged in the connecting member mounting portion.

前記連結部材と前記連結部材装着部のそれぞれに係合部を設け、これらの係合部の係合により、前記板部材の前記ブレードラバーからの脱落が防止されるようにしてもよい。
前記連結部材は、前記ブレードラバーの一部として前記ブレードラバーの他の部分と一体に形成された連結部であってもよい。 An engaging portion may be provided in each of the connecting member and the connecting member mounting portion, and the engagement of these engaging portions may prevent the plate member from falling off the blade rubber.
The connecting member may be a connecting part integrally formed with another part of the blade rubber as a part of the blade rubber.

本発明によれば、ワイパーブレードに備えられる板部材（例えば、バーティブラ１０）が、複数の板部材片（例えば、板部材片１１）を連結部材（例えば、連結部材１２）で連結して構成されるので、異なる曲率半径を有する複数の板部材片を予め用意しておけば、板部材全体の形状や長さに応じて適切な板部材片を組み合わせることにより、複雑な湾曲形状を有する板部材を容易に形成することができる。したがって、１つの板部材全体を複雑な湾曲形状に加工して形成するのと比較して、製造効率が著しく向上し、大幅なコスト削減を図り得る。また、この場合、個々の板部材片は、全体が特定の曲率半径を有する単純な湾曲形状のものとすれば良いので、比較的容易且つ低コストで形成しておくことができる。 According to the present invention, the plate member (for example, the vertebra 10) provided in the wiper blade is configured by connecting a plurality of plate member pieces (for example, the plate member piece 11) with the connecting members (for example, the connecting member 12). Therefore, if a plurality of plate member pieces having different radii of curvature are prepared in advance, a plate member having a complicated curved shape can be obtained by combining appropriate plate member pieces according to the shape and length of the whole plate member. Can be easily formed. Therefore, the manufacturing efficiency can be remarkably improved and the cost can be greatly reduced as compared with the case where one whole plate member is processed and formed into a complicated curved shape. Further, in this case, the individual plate member pieces may be formed in a simple curved shape having a specific radius of curvature as a whole, and can be formed relatively easily and at low cost.

また、連結部材と板部材片の端部（例えば、板部材片１１の端部１１Ａ）のそれぞれに係止部（例えば、板部材片１１の突起部１１Ｂと連結部材１２の係止穴１２Ｄ、又は板部材片１１の係止穴１１Ｃと連結部材１２の突起部１２Ｇ）を設ければ、これらの係止部の係合により、板部材片の連結部材からの脱落を適切に防止できる。 In addition, each of the connecting member and the end of the plate member piece (for example, the end 11A of the plate member piece 11) has a locking portion (for example, the protrusion 11B of the plate member piece 11 and the locking hole 12D of the connecting member 12). Alternatively, if the locking hole 11C of the plate member piece 11 and the protruding portion 12G of the connecting member 12 are provided, the plate member piece can be appropriately prevented from falling off the connecting member by the engagement of these locking portions.

また、ブレードラバー（例えば、ブレードラバー２０）に、連結部材が装着される連結部材装着部（例えば、連結部材装着部２４）を備え、連結部材と連結部材装着部のそれぞれに係合部（例えば、連結部材１１の切り欠き部１２Ｉと連結部材装着部２４の段部２４Ａ）を設ければ、これらの係合部の係合により、連結部材の連結部材装着部からの脱落（ひいては、板部材のブレードラバーからの脱落）を適切に防止できる。 Further, the blade rubber (for example, the blade rubber 20) includes a connecting member mounting portion (for example, the connecting member mounting portion 24) to which the connecting member is mounted, and each of the connecting member and the connecting member mounting portion has an engaging portion (for example, If the notch portion 12I of the connecting member 11 and the stepped portion 24A of the connecting member mounting portion 24 are provided, the engagement of these engaging portions causes the connecting member to fall off from the connecting member mounting portion (and hence the plate member). Can be appropriately prevented from falling off the blade rubber.

また、連結部材をブレードラバーの一部としてブレードラバーの他の部分と一体に形成された連結部（例えば、連結部２５）とすれば、ワイパーブレードを構成する部品点数を削減できるとともに、板部材のブレードラバーからの脱落をより確実に防止できる。 Further, if the connecting member is a part of the blade rubber and is a connecting part (for example, the connecting part 25) formed integrally with the other part of the blade rubber, the number of parts constituting the wiper blade can be reduced, and the plate member Can be more reliably prevented from falling off the blade rubber.

以下、添付図面に基づいて本発明の実施形態について説明する。
図１には、本発明の実施形態のワイパーブレードにおける一対のバーティブラ１０を示す。また、図２には、本発明の実施形態のワイパーブレードにおけるブレードラバー２０を示す。なお、本実施形態は、バーティブラ１０及びブレードラバー２０の構成に特徴を有するものであるため、支持部材を含むワイパーブレードの全体構成の図示及び説明はしていない。すなわち、本発明において、支持部材の形態は特に限定されるものではなく、例えば図９に示したような複数のレバー部材からなる支持部材の他にも、ブレードラバー２０に沿って一体に装着されるタイプの支持部材等、様々な形態の支持部材を採用することができる。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 shows a pair of vertebras 10 in a wiper blade according to an embodiment of the present invention. FIG. 2 shows a blade rubber 20 in the wiper blade according to the embodiment of the present invention. In addition, since this embodiment has the characteristics in the structure of the vertebra 10 and the blade rubber 20, the illustration and description of the whole structure of the wiper blade containing a supporting member are not carried out. That is, in the present invention, the form of the support member is not particularly limited. For example, in addition to the support member composed of a plurality of lever members as shown in FIG. 9, the support member is integrally mounted along the blade rubber 20. Various types of support members, such as a type of support member, can be employed.

図１に示されるように、一対のバーティブラ１０は、それぞれ、複数の板部材片１１（本実施形態においては各バーティブラ１０について１１個の板部材片１１ａ〜１１ｋ）を、複数の連結部材１２（本実施形態においては各バーティブラ１０について１０個の連結部材１２）で連結して構成されている。 As shown in FIG. 1, each of the pair of vertebras 10 includes a plurality of plate member pieces 11 (in this embodiment, eleven plate member pieces 11 a to 11 k for each vertebra 10) and a plurality of connecting members 12 ( In the present embodiment, each vertebra 10 is connected by 10 connecting members 12).

各板部材片１１ａ〜１１ｋは、金属製の細長い板状の部材であり、それぞれが固有の曲率半径（Ｒ）を有している。これらの板部材片１１ａ〜１１ｋを長手方向に連ねて連結することにより、長手方向の各位置において異なる曲率半径を有する複雑な湾曲形状のバーティブラ１０が形成される。具体的な製造工程においては、板部材片１１として、異なる曲率半径の湾曲形状を有する複数の板部材片１１を予め用意しておき、完成形のバーティブラ１０における長手方向の各位置において必要とされる湾曲形状（曲率半径）に応じて、その曲率半径を有する板部材片１１を選択し、選択された板部材１１を連結部材１２で連結して組み合わせることにより、バーティブラ１０が形成されることになる。 Each of the plate member pieces 11a to 11k is an elongated plate-like member made of metal, and each has a unique radius of curvature (R). By connecting these plate member pieces 11a to 11k so as to be connected in the longitudinal direction, a complicated curved vertebra 10 having a different radius of curvature at each position in the longitudinal direction is formed. In a specific manufacturing process, a plurality of plate member pieces 11 having curved shapes having different radii of curvature are prepared in advance as the plate member pieces 11, and are required at each position in the longitudinal direction of the completed vertebra 10. In accordance with the curved shape (curvature radius) to be selected, the plate member piece 11 having the curvature radius is selected, and the selected plate member 11 is connected and combined by the connecting member 12 to form the vertebra 10. Become.

なお、図１においては、複数の板部材片１１について、それぞれが異なる曲率半径を持ち得るという意味で、各板部材片１１に小文字のアルファベットを付して示している。一方、複数の連結部材１２は、同一の形態のものが用いられているため、同一の符号を付して示している。 In FIG. 1, a plurality of plate member pieces 11 are shown with lower case alphabets attached to the plate member pieces 11 in the sense that each plate member piece 11 may have a different radius of curvature. On the other hand, since the thing with the same form is used for the some connection member 12, the same code | symbol is attached | subjected and shown.

図２に示されるように、ブレードラバー２０は、ゴム製の長尺部材であり、本体部２１と、本体部２１の下面に形成されたブレード部２２とを備えている。ブレードラバー２０は、本体部２１において支持部材（図示せず）により支持されるとともに、ワイパーブレードの使用時には、ブレード部において被払拭面（例えば自動車のガラス面）に接触して、被払拭面の払拭を行うものである。 As shown in FIG. 2, the blade rubber 20 is a long rubber member, and includes a main body portion 21 and a blade portion 22 formed on the lower surface of the main body portion 21. The blade rubber 20 is supported by a support member (not shown) in the main body 21, and when the wiper blade is used, the blade rubber 20 comes into contact with the surface to be wiped (for example, the glass surface of an automobile) and Wiping is performed.

本体部２１の両側側面には、バーティブラ１０が装着されるための溝部２３が形成され、本体部２１の長手方向全体にわたって延びている。また、本体部２１両側の溝部２３上の所定箇所には、複数の連結部材装着部２４が形成されている。これにより、バーティブラ１０を溝部２３内に装着したとき、バーティブラ１０を構成する複数の連結部材１２が、それぞれ対応する連結部材装着部２４内に配置されるようになっている。 Grooves 23 for mounting the vertebra 10 are formed on both side surfaces of the main body 21 and extend over the entire length of the main body 21. A plurality of connecting member mounting portions 24 are formed at predetermined locations on the groove portions 23 on both sides of the main body portion 21. Thus, when the vertebra 10 is mounted in the groove 23, the plurality of connecting members 12 constituting the vertebra 10 are arranged in the corresponding connecting member mounting portions 24, respectively.

図３には、連結部材１２を上側から見た斜視図を、また図４には、連結部材１２を下側から見た斜視図を、それぞれ示す。また、図５には、連結部材１２に対する板部材片１１の連結の様子を断面図で示す。 3 is a perspective view of the connecting member 12 as viewed from above, and FIG. 4 is a perspective view of the connecting member 12 as viewed from below. FIG. 5 is a cross-sectional view showing how the plate member piece 11 is connected to the connecting member 12.

図示されるように、連結部材１２は、例えば樹脂成形により形成される略直方体形状の部材であり、前後両側の端面１２Ａに、板部材片１１の端部１１Ａが嵌合する嵌合穴１２Ｂを備えている。本実施形態においては、両側の嵌合穴１２Ａは、連結部材１２の内部で連通して、１つの嵌合穴となっている。これにより、１つの連結部材１２に取り付けられた隣接する板部材１１の対向する末端部分が、連結部材１２の内部で当接して配置されるようになっている。 As shown in the figure, the connecting member 12 is a substantially rectangular parallelepiped member formed by, for example, resin molding. I have. In this embodiment, the fitting holes 12A on both sides communicate with each other inside the connecting member 12 to form one fitting hole. Thereby, the opposing terminal portions of the adjacent plate members 11 attached to one connecting member 12 are arranged in contact with each other inside the connecting member 12.

連結部材１２には、嵌合穴１２Ｂに隣接して、一対の係止穴１２Ｄが形成されている。係止穴１２Ｄは、嵌合穴１２Ｂが開口する端面１２Ａに隣接した位置に形成され、嵌合穴１２Ｂの下側側面１２Ｅから連結部材１２の下面１２Ｃにかけて貫通して延びている。一方、板部材片１１の端部１１Ａには、突起部１１Ｂが形成されている。これにより、端部１１Ａが嵌合穴１２Ｂ内に装着されたとき、突起部１１Ｂが係止穴１２Ｄ内に係合して、板部材片１１の連結部材１２からの脱落が防止されるようになっている。 The connecting member 12 is formed with a pair of locking holes 12D adjacent to the fitting hole 12B. The locking hole 12D is formed at a position adjacent to the end surface 12A where the fitting hole 12B opens, and extends through the lower side surface 12E of the fitting hole 12B to the lower surface 12C of the connecting member 12. On the other hand, a protrusion 11 B is formed at the end 11 A of the plate member piece 11. Thereby, when the end portion 11A is mounted in the fitting hole 12B, the protruding portion 11B is engaged in the locking hole 12D so that the plate member piece 11 is prevented from falling off the connecting member 12. It has become.

以上のように、本実施形態のワイパーブレード１によれば、バーティブラ１０が複数の板部材片１１を連結部材１２で連結して構成されるので、異なる曲率半径を有する板部材片１１を複数用意しておけば、バーティブラ１０の全体形状に応じて適切な板部材片１１を組み合わせることにより、複雑な湾曲形状を有するバーティブラ１０を容易に形成することができる。すなわち、本実施形態のワイパーブレード１では、幾つかの種類の板部材片１１を予め用意しておけば、全体として異なる形状や長さを有する様々な種類のバーティブラ１０を容易に形成することができるので、１本のバーティブラ全体を複雑な形状に加工して形成するのと比較して、製造効率が著しく向上し、大幅なコスト削減を図り得る。また、この場合、個々の板部材片１１は、全体が特定の曲率半径を有する単純な湾曲形状のものとすれば良いので、比較的容易且つ低コストで形成することができる。 As described above, according to the wiper blade 1 of the present embodiment, the vertebra 10 is configured by connecting a plurality of plate member pieces 11 with the connecting members 12, and thus a plurality of plate member pieces 11 having different radii of curvature are prepared. By doing so, it is possible to easily form the vertebra 10 having a complicated curved shape by combining appropriate plate member pieces 11 according to the overall shape of the vertebra 10. That is, in the wiper blade 1 of the present embodiment, if several types of plate member pieces 11 are prepared in advance, various types of vertebra 10 having different shapes and lengths as a whole can be easily formed. Therefore, the manufacturing efficiency can be remarkably improved and the cost can be greatly reduced as compared with the case where one entire vertebra is processed into a complicated shape. Further, in this case, the individual plate member pieces 11 may be formed in a simple curved shape having a specific curvature radius as a whole, and can be formed relatively easily and at low cost.

図６には、本発明の他の実施形態を示す。本実施形態では、上記図１から図５に示す実施形態と比較して、板部材片１１と連結部材１２との係合に関する構成のみが異なっている。具体的に、本実施形態において、連結部材１２は、嵌合穴１２Ｂの上側側面１２Ｆから嵌合穴１２Ｂの内部に向けて突出する突起部１２Ｇを備えている。一方、板部材片１１の端部１１Ａには、板部材片１１を上下に貫通する係止穴１１Ｃが形成されている。このような構成により、板部材片１１の端部１１Ａと連結部材１２の嵌合穴１２Ｂに嵌合させたとき、板部材片１１の係止穴１１Ｃに連結部材１２の突起部１２Ｇが係合して、板部材片１１の連結部材１２からの抜け止めがなされるようになっている。 FIG. 6 shows another embodiment of the present invention. In this embodiment, compared with the embodiment shown in FIGS. 1 to 5, only the configuration relating to the engagement between the plate member piece 11 and the connecting member 12 is different. Specifically, in the present embodiment, the connecting member 12 includes a protrusion 12G that protrudes from the upper side surface 12F of the fitting hole 12B toward the inside of the fitting hole 12B. On the other hand, the end 11 A of the plate member piece 11 is formed with a locking hole 11 C penetrating the plate member piece 11 up and down. With such a configuration, when the end portion 11A of the plate member piece 11 and the fitting hole 12B of the connecting member 12 are fitted, the protruding portion 12G of the connecting member 12 is engaged with the locking hole 11C of the plate member piece 11. Thus, the plate member piece 11 is prevented from coming off from the connecting member 12.

なお、上記図５及び図６の実施形態では、板部材片１１と連結部材１２のそれぞれに係止部（図５における板部材片１１の突起部１１Ｂ及び連結部材１２の係止穴１２Ｄ、又は図６における板部材片１１の係止穴１１Ｃ及び連結部材１２の突起部１２Ｇ）を備え、これらの係止部の係合により、板部材片１１の連結部材１２からの脱落を防止するようにしたが、このような係止部は、本発明にとって必須の構成ではなく、例えば板部材１１の端部１１Ａが、連結部材１２の嵌合穴１２Ｂに嵌め込まれるだけで、摩擦力により保持されるような構成をとっても構わない。 5 and 6, the plate member piece 11 and the connecting member 12 are each provided with a locking portion (the protrusion 11B of the plate member piece 11 and the locking hole 12D of the connecting member 12 in FIG. 6 is provided with a locking hole 11C of the plate member piece 11 and a protruding portion 12G of the connecting member 12, and the engagement of these locking portions prevents the plate member piece 11 from falling off the connecting member 12. However, such a locking portion is not an essential configuration for the present invention. For example, the end portion 11A of the plate member 11 is held by the frictional force only by being fitted into the fitting hole 12B of the connecting member 12. You may take such a structure.

図７には、本発明の更に他の実施形態を示す。本実施形態では、連結部材１２とブレードラバー２に対して、ブレードラバー２の連結部材装着部２４からの連結部材１２の脱落を防止するための構成（係合部）が備えられる。詳しく説明すると、連結部材１２の外側側面１２Ｈ（連結部材１２が連結部材装着部２４内に配置されたとき、ブレードラバー２０の外側を向く側面）の長手方向両側の端辺部分には、連結部材１２側の係合部として、切り欠き部１２Ｉが形成されている。一方、連結部材装着部２４の開口部分の長手方向両側の端部には、連結部材装着部２４側の係合部として、段部２４Ａが形成されている。 FIG. 7 shows still another embodiment of the present invention. In the present embodiment, the connection member 12 and the blade rubber 2 are provided with a configuration (engagement portion) for preventing the connection member 12 from dropping from the connection member mounting portion 24 of the blade rubber 2. More specifically, the connecting member 12 has an outer side surface 12H (a side surface facing the outer side of the blade rubber 20 when the connecting member 12 is disposed in the connecting member mounting portion 24) on both ends in the longitudinal direction. A notch 12I is formed as an engaging portion on the 12 side. On the other hand, a step portion 24A is formed as an engaging portion on the connecting member mounting portion 24 side at both ends in the longitudinal direction of the opening portion of the connecting member mounting portion 24.

このような構成により、連結部材１２が連結部材装着部２４内に装着されると、段部２４Ａが連結部材１２の切り欠き部１２Ｉに係合するので、連結部材１２の連結部材装着部２４からの脱落防止（すなわち、バーディブラ１０の溝部２３からの脱落防止）がなされるようになっている。 With such a configuration, when the connecting member 12 is mounted in the connecting member mounting portion 24, the stepped portion 24 A engages with the notch portion 12 I of the connecting member 12, and thus from the connecting member mounting portion 24 of the connecting member 12. Is prevented from falling out (that is, from falling off the groove 23 of the birdie bra 10).

ここで、バーティブラ１０における連結部材１２部分は、例えば樹脂製のものであり、適切な係合部を有するように加工しやすいものであるので、容易に、係合部（切り欠き部１２Ｉ）を形成することができる。また、ブレードラバー２０は、可撓性を有するゴム製の部材であるので、連結部材装着部２４に段部２４Ａが設けられていても、ブレードラバー２０を変形することにより、連結部材１２の装着を行うことができる。 Here, the connecting member 12 portion in the vertebra 10 is made of, for example, resin and is easily processed so as to have an appropriate engaging portion. Therefore, the engaging portion (notch portion 12I) can be easily formed. Can be formed. Further, since the blade rubber 20 is a flexible rubber member, even if the connecting member mounting portion 24 is provided with the stepped portion 24A, the blade rubber 20 is deformed so that the connecting member 12 is mounted. It can be performed.

なお、上記図７の実施形態においては、連結部材１２の切り欠き部１２Ｉとブレードラバー２０の段部２４Ａとを係合部としたが、本発明における係合部の構成は、このような形態に限定されるものではなく、連結部材１２の連結部材装着部２４からの脱落を防止するようなものであれば、任意の形態の係合部を採用することができる。 In the embodiment of FIG. 7 described above, the notch portion 12I of the connecting member 12 and the stepped portion 24A of the blade rubber 20 are the engaging portions, but the configuration of the engaging portion in the present invention is such a form. However, the present invention is not limited to this, and any type of engaging portion can be adopted as long as it prevents the connecting member 12 from falling off the connecting member mounting portion 24.

図８には、本発明の更に他の実施形態を示す。本実施形態においては、板部材片１１を連結する連結部材は、ブレードラバー２０の連結部材装着部の部分に、ブレードラバー２の他の部分と一体に形成された連結部２５となっている。すなわち、本実施形態においては、複数の板部材片１１が、ブレードラバー２０の一部である連結部２５において連結されることにより、バーティブラ１０が形成されるようになっている。なお、連結部２５に対する板部材片１１の組み付けは、ゴム製のブレードラバー２０を変形させて行われることになる。 FIG. 8 shows still another embodiment of the present invention. In the present embodiment, the connecting member for connecting the plate member pieces 11 is a connecting portion 25 formed integrally with the other portion of the blade rubber 2 at the connecting member mounting portion of the blade rubber 20. That is, in the present embodiment, the plurality of plate member pieces 11 are connected to each other at the connecting portion 25 that is a part of the blade rubber 20, whereby the vertical bra 10 is formed. The assembly of the plate member piece 11 to the connecting portion 25 is performed by deforming the rubber blade rubber 20.

このように、図８の実施形態によれば、連結部材が、ブレードラバー２０に一体に組み込まれた連結部２５となっているので、ワイパーブレードを構成するための部品点数を削減することができる。また、バーティブラのブレードラバー２からの脱落は、更に生じにくくなる。なお、本実施形態における連結部２５は、ブレードラバー２０の一部として構成されている以外の点では、例えば上記各実施形態における連結部材１２と同様の構成を有するものとすればよい。 As described above, according to the embodiment of FIG. 8, the connecting member is the connecting portion 25 integrally incorporated in the blade rubber 20, so that the number of parts for configuring the wiper blade can be reduced. . Further, the vertebra is not easily detached from the blade rubber 2. In addition, the connection part 25 in this embodiment should just have the structure similar to the connection member 12 in each said embodiment except the point comprised as a part of blade rubber 20, for example.
